Here are couple of Class-T amp I put together - took a while to complete. Nothing too fancy, just couple of piece-together metal/plywood box with Sure TK2050-4x100 Class-T boards.

The one with linear power supply I clobbered together and was surprised it worked. It took me several iterations before settling down. It is just an unregulated supply with hopefully sufficient smoothing caps. The other one is powered with hacked computer power supply - two supplies serially connected together using only the 12-volt lines, yielding 24-volt at, I believe, 15A (i forgot, it has been awhile since I pieced them together).

Here's the 8 channel build using SDS-258 and CDA-258 completed 3 weeks ago. The SQ is better than XPA-5 it replace. Better separation and detail. SDSf are used to power LCR and CDA for surround. I put 2 Nexus silent 80mm fan on top amp module as it's quite hot. Casing is a hack desktop PC casing.

Here are a few pics of my latest amp. A stereo, class D based on the LJM design, using a SMPS and speaker protection board from Cristi at connexelectronic . Using 72vdc rails for ~200wpc into 8 ohms. Sounds great and is dead silent. I can't audibly detect any hiss, hum or other noise. Presently, I'm testing it (non-critically) with my new Doug Self 2012 preamp I recently completed. With the completion of this project, I now have a nice stackable system using this popular form factor enclosure.

But I started to change a few xover components and left them hanging before gluing them to the back. The sound was clearer. And then I glued them down and the sound became blurred a bit. Lift them off and hang them: cleaner sound. Same parts.
So I took off and hung all the xover parts. Cleaner, clearer sound.

Next I unmounted and hung the amp and PS. Result: Cleaner clearer sound.

It looks ugly, but its on the back of the speaker where no one can see it.
